When the developer replenishing container 3 is mounted thereon, it is pushed by the projection 33 of the developer replenishing container 3,
The lock member 7 rotates against the elastic member 9 in the direction of the arrow (clockwise) shown in FIG. 9A around the rotation center 74, and the projection 33 and the lock member claw 73 are engaged with each other. As shown in b), the developer replenishing container 3 is locked so that it cannot be removed. When the lock member 7 rotates clockwise, the claw 71 also rotates at the same time, and in the locked state of the replenishing container 3 shown in FIG. The opening / closing lid 2 can be slidably opened / closed.

When the sheet 5 is pulled in the direction of the arrow in FIG. 5, the portion of the sheet 5 fixed to the opening of the container body 3a is sequentially peeled from the folded side thereof, and as shown in FIG. The folded position moves in the pull-out direction, and the folded portion of the sheet 5a pushes the open / close lid 4 and moves in the opening direction. Then, the opening of the developer replenishing container 3 is gradually opened, and the developer contained in the container main body 3a is dropped and replenished to the developer receiving container 1.

A container main body for storing the developer, a sealing sheet peelably fixed to the periphery of the container main body opening, and a sheet drawer member fixed to the sheet end and detachably attached to the container main body; The opening / closing lid has an engaging portion, and the engaging portion is provided on the sheet pull-out member just before the end of the opening operation of the opening / closing lid. A developer replenishing device, wherein the sheet draw-out member is pulled out of the developer replenishing container when the opening operation of the opening / closing lid is completed, and a developer replenishing container removably set in the replenishing device. In Although,
By such means, the portion serving as a handle for pulling out the seal of the developer replenishing container is engaged with the lid just before the opening and closing of the opening and closing lid of the receiving container, and is detached from the replenishing container with the opening movement, When the operator peels off the sheet and replenishes the developer into the receiving container, the opening and closing lid of this receiving container is already open, so the tip and upper part of the opening and closing lid may be soiled with the developer. When the developer disappears, scattering and leakage of the developer can be prevented.

が周囲を汚染することもない。The above-described embodiment is directed to a developer replenishing apparatus including a developer replenishing opening and a developer receiving container having a sliding opening / closing lid A for covering the opening. A developer replenishing container having a container main body for accommodating the developer and a developer replenishing container having a slide-type opening / closing lid B covering the container main body opening is detachable, and the developer receiving container is urged by an elastic member. When the developer replenishing container is mounted on the developer receiving container, the lock member 1 and a part of the main body of the developer replenishing container are engaged with each other so that the developer replenishing container cannot be removed. At the same time, the lock member 2, which is engaged with the slide-type opening / closing lid A and prohibits the opening / closing of the opening / closing lid A, is disengaged by a part of the main body of the developer replenishing container to open / close the opening / closing lid A. The opening / closing lid A By pushing further than the closed state to the unlocked position, the locking member 1 and the developer supply device developer replenishing container body and the engagement is solved for, characterized in that the developer replenishing container becomes removable, and,
Since the developer replenishing container is detachably set to the developer replenishing container, the developer replenishing container is locked when the developer replenishing container is mounted on the developer receiving container, and the developer replenishing container cannot be removed. Is released only by pushing the open / close lid A from the closed state to the unlock position, so only when the open / close lid is securely closed,
The developer replenishing container can be removed. Therefore, the developer replenishing container does not come off when the opening / closing lid is in the half-open state, and the developer does not contaminate the surroundings.

In the step of placing the replenishing container 3 on the receiving container 1 and holding it down from above, and locking the protruding portion 33 to the lock 7 (FIG. 11A), the projecting portion 34 The elastic member (leaf spring) 8 provided at the place 102 is pushed downward, and is elastically deformed as shown in FIG. Accordingly, when the replenishing container 3 is set at a replenishing position for receiving the developer and replenishing the developer to the container 1, the resilient member 8 allows the container projecting portion 3b inserted into the recess 14 to be moved. As a rotation fulcrum, it receives an elastic biasing force in a direction of ascending upward from the supply position. However, as long as the lock member 7 locks the projection 33 and locks the replenishing container 3, the above-described rotation and rise is prevented.

At the same time, FIG.
Due to the elastic force of the elastic member 8 shown in (b), the developer replenishing container 3 automatically rotates upward from the developer replenishing position of the developer receiving container 1 as described above. The operator can confirm that the lock has been released by automatically displacing the developer replenishing container 3 from the developer replenishing position.
【００３９】而して作業者は、このように自動変位した
